Description

Closure arrangement for the bearing housing of a transverse roller bearing with a spherically curved outer surface

The innovation concerns an arrangement for the frontal Closure of a bearing housing for form-fitting reception a transverse roller bearing with a spherically curved outer surface of his outer race, with the bearing housing from its largest Inner diameter reaching up to the end face to be closed diametrical extensions of its spherical inner surface

for inserting the roller bearing in by 90 points.

For fastening the closure lids or caps of such arrangements a wide variety of fasteners are known. . .All these fasteners are essentially '" characterized in that they lie in the same radial plane as the two parts to be connected with their help. This means ^ either that the fastening means must consist of separate resilient parts or that the parts to be connected must be made with fairly great precision in order to avoid permanent deformations resulting from the connection.

The task of the innovation is without the use of special parts the greatest possible flexibility of the fastening means achieve. According to the innovation, this object is achieved by that a frustoconical widening towards its opening Closing cap at least two of axial extensions the frustoconical shell wall formed, diametrically has projections lying on the circumference of the cap, with which the cap engages in the extensions of the inner surface of the housing.

The closure arrangement according to the invention is characterized by great, simplicity and cheapness to manufacture. she is explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show there:

Fig. 1 shows a closure cap 1 for a bearing housing 2 for Support of a ball bearing, the outer race of which 3 has a Has spherically curved outer surface. The bearing housing 2 is with two diametrically opposed extensions 4,5 its inner surface through which the introduction of the Bearing in a manner known per se in a rotated by 90 ° Position to the final position in the housing ^ is made possible. The extensions extend from the housing face to be closed axially inwards to the largest diameter of the spherical inner surface of the housing and take the Means for fastening the closure cap. The extensions are made when casting the case, whatever it comes with

that brings the diametrical distance between the base surfaces the extensions 4.5 with relatively large tolerances fluctuates.

The fastening means of the closure cap are formed by axial projections 6, 7 of the frustoconical casing wall 8 of the cap. Only these projections 6, 7 lie in the same radial plane as the bearing housing. In the radial plane of the cap edge 10 and the end face 9 of the bearing housing 2, these two elements form a sealing surface. The closure cap 1 is attracted against the bearing housing 2 by the axial force generated by the projections 6, 7 and rests resiliently against the bearing housing. The extension * ¹ ^^ in the bearing housing 2 can have base surfaces converging towards the housing face 9 to be closed in order to adapt to the direction of the projections 6, 7, or they can also be interrupted by indentations 11, as shown in FIG. 2, behind which the projections 6,7 snap into place.

In both cases, the ^{axial force required to press the 1} closure cap against the end face 9 of the bearing housing 2 is caused by the frustoconical design of the jacket wall 8 of the closure cap 1. As a result, the projections 6, 7 are also directed obliquely outwards, so that an axial force is generated wherever the projections engage in the bearing housing 'or behind the recesses' 11. This means that 'the deviations in the dimensions of the base of the extension. 4.5 can be relatively large without endangering the engagement of the closure cap 1 in the bearing housing 2. When the closure cap 1 is inserted into the bearing housing 2, it will spring in as shown in FIGS. 3 and 4. Ficht only the projections 6, 7 'but the entire closure cap' takes part in this deflection, which is easily possible since the deformed sections 13 and 14 of the closure cap lie outside the bearing housing 2. The deflection capacity is greater than if only the relatively low springiness of the fastening means is used alone as in the known locking arrangements *
